Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
The present invention is mainly used in the upgrading of telepoint base station.Usually, guarantee that the corresponding levels and next stage RRU are to be finished by the optical interface module on the RRU by optical fiber and BBU reliable communication.And the optical interface module software is bigger usually, and a plurality of RRU may start simultaneously, after so if RRU starts all to BBU request software then the increase that may cause that network is busy, BBU loads, so the optical interface module is put on the built-in memory of RRU, only in the needs upgrading, just obtains new version software from BBU.
On the memory of RRU, deposit a text, such as RruSwVer.ini.Can put into the upgrade status of optical interface module software in the file, read and write for high layer software and startup software.For example, wherein the upgrading sign of every kind of software can define like this:
typedef?struct?tagOamCfgParamStruc
{
OSS_CHAR szName[20]; / * dbase */
OSS_CHAR szFlag ；/*‘＝’*/
OSS_CHAR szValue; / * ' 0 ' expression normal state; ' 1 ' for upgrading attitude */
OSS_CHAR szEnd ；/*‘\n’*/
}TOamCfgParam，*PTOamCfgParam；
Fig. 1 is a flow chart of the present invention.As shown in Figure 1, the present invention includes following steps:
(a) RRU loads the optical interface module software of current version on the internal memory, waits for afterwards and communicating by letter normally with BBU.
(b) RRU reports the software version number of optical interface module to BBU; BBU judges the optical interface module software according to the version number that reports up, and whether needs are upgraded and notice RRU.
(c) if the optical interface module software needs upgrading, then RRU obtains software from BBU; Otherwise skip following software upgrading step and directly enter follow-up startup flow process.
